    2005 115hp wiring.

    I’ve looked over this over and over trying to make sense of it and I feel like I’m missing something. The trim/oil harness near the gauges has no connectors, they’re split up and go all over. Even if it did, the only wires from the harness on the engine right now would be the green and...

    2005 115hp wiring.

    1A / 1B - 2 pin -I don’t know what this is. 2A / 2B - 4 pin connector. Low oil indicator? This is the 4 pin connector I’m assuming you’re talking about and even though it fits, maybe I’m not using it correctly? 3B - outdated trim/oil harness. Unplugged.

    2005 115hp wiring.

    Thank you for the reply. My 10 pin works great. Boat starts, runs, tach works. Does the alarm signal for overheating go through the 10-pin? I attached a photo of the old trim/oil harness hanging out of the back of my boat before I plugged the green one into the only 4 pin connector that...

    2005 115hp wiring.

    My understanding is that this is the overheat switch. I just couldn’t get it to activate the alarm.

    2005 115hp wiring.

    Yamaha F115TLRD. Manufactured in 2004 but I realized later that it’s a 2005 model if I’m not mistaken. I have 2 concerns after repower. I used to have a 1999 2 stroke Yamaha before. So my harness isn’t a perfect match with what I had before. I see other people have this problem and I’ve...

    Tachometer on new engine seems wrong.

    I went from a yamaha 2002 90 tlr to a yamaha 1999 b115tlr I never had any issues with the tach before. On this new engine thought my tachometer goes off the chart at higher speeds. I found that you can calibrate it but I seem to be already as high as the tach can go, 6P. All other settings...

    Overheat alarm with cold water coming out of engine

    1999 yamaha 115 inshore with a bobs machine stabilizer plate. I had an overhear alarm yesterday go off so I shut it down immediately and waited a while. I am pretty sure I’m under propped because at half throttle the tachometer says 6000. So I back off to 5500 max. Still trying to get a...

    Mystery lower unit

    I bought a 1999 2 stroke yamaha 115. It has a low water pickup on the lower unit. Bobs machine says it’s not their nose cone and it’s a stock part, but I’ve never seen another lower unit look like this. I can’t get the photo to upload, but basically the water intake isn’t on the side up...

    Salt Water destroyed my engine. Quuestions.

    So my Yamaha 2002 90TLR is basically worthless now I think. I had low compression, took the head off and cylinders 2 and 3 have damage to the sleeves. The water passages on the side of those cylinders are completely blocked up with salt deposits. I do flushes after but I don't know how much...

    Question about Yamaha Fuel Pump

    My boat uses this fuel pump. I have a question about it. https://www.crowleymarine.com/parts/442207.cfm For testing, with it not bolted to the engine with the gasket, I squeezed the fuel line bulb and the fuel pump leaks. The leak seems to start in the area of where the bolts are supposed...

    Motors runs for a second and won't keep going.

    I have a 2002 90TLR 2 Stroke Yamaha Outboard. It ran very well last year. This year, not so much. Took it out a month ago. It didn't want to start so I gave it a bit of starter fluid to get the fuel flow going. I know, not exactly ideal but I couldn't seem to get the primer to get fuel to...

    Low RPMs at WOT

    Here's a pic of my linkage for the CDI. In this photo I have the controller about half way forward, around the spot that I lose RPMs. What do those notches that I'm at mean? When I got WOT it actually goes all the way over to the left where I have marked "WOT?"

    Low RPMs at WOT

    I've been running my boat for a couple years like this but really don't think it's running full strength. 24' Pontoon, 2002 90 HP TLR 2 Stroke. Symptoms. - Max RPM is 4000 at WOT. 13 MPH with just a few people on it. - Max RPM is down to 3000 if I have put a lot of people on it. Goes about...

    Yamaha Outboard Water Hose goes to nowhere

    I don't understand how my 2002 90 HP 2 Stroke TLRA has worked these last few years. I'm chasing a different problem but when I took the lower unit off I was expecting to have to disconnect the water hose that pushes water back up to the engine from the water pump. It isn't connected though...
